Corruption is on the rise in Africa, with South Africa topping the list of countries where citizens believe the problem has got worse in the last year, said a Transparency International survey released Tuesday.

According to the report, 83 percent of South Africans interviewed felt that corruption had increased, with Ghana and Nigeria also among the worst-affected nations.

Across all 28 countries surveyed, the police, business executives, government officials and the courts were all perceived as corrupt, with 75 million people estimated to have paid a bribe in the past year.
